This happens quite a lot in Belfast, where the kind of Taqwa aura separates Irish Muslims from the crowd rather strikingly. They look exactly the same, but I can just tell that they are muslim, and the only difference is the fact that they know that Allah is watching them, and is with them, which is something that I know as well, and other people don't. Maybe that's it. Muslims don't feel alone, Taqwa reminds them that they are all part of the same tapestry, and that while they may not shine to themselves, somewhere out there, someone is watching them sparkle against the backdrop of infinity.
